/**
 * Structure describing supported external semaphore handle features.
 * 
 * Description
 * 
 * If {@code handleType} is not supported by the implementation, then {@link VkExternalSemaphorePropertiesKHR}{@code ::externalSemaphoreFeatures} will be set to zero.
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code sType} must be {@link KHRExternalSemaphoreCapabilities#VK_STRUCTURE_TYPE_EXTERNAL_SEMAPHORE_PROPERTIES_KHR STRUCTURE_TYPE_EXTERNAL_SEMAPHORE_PROPERTIES_KHR}
 * {@code pNext} must be {@code NULL}
 * 
 * 
 * See Also
 * 
 * {@link KHRExternalSemaphoreCapabilities#vkGetPhysicalDeviceExternalSemaphorePropertiesKHR GetPhysicalDeviceExternalSemaphorePropertiesKHR}
 * 
 * Member documentation
 * 
 * 
 * {@code exportFromImportedHandleTypes} – a bitmask of {@code VkExternalSemaphoreHandleTypeFlagBitsKHR} specifying which types of imported handle {@code handleType} can be exported from.
 * {@code compatibleHandleTypes} – a bitmask of {@code VkExternalSemaphoreHandleTypeFlagBitsKHR} specifying handle types which can be specified at the same time as {@code handleType} when creating a semaphore.
 * {@code externalSemaphoreFeatures} – a bitmask of {@code VkExternalSemaphoreFeatureFlagBitsKHR} describing the features of {@code handleType}.
 *
